At 500 PM HST (0300 UTC), the center of Tropical Storm Olivia was
located near latitude 21.9 North, longitude 149.7 West. Olivia is
moving toward the west near 10 mph (17 km/h). A continued west to
west-southwest motion is expected for the next few days. On the
forecast track, Olivia will be moving over the main Hawaiian Islands
late Tuesday night into Wednesday.
 
Maximum sustained winds are near 70 mph (110 km/h) with higher
gusts.  Gradual weakening is forecast during the next 48 hours, but
Olivia is expected to remain a tropical storm as it moves across
the islands.
 
Tropical-storm-force winds extend outward up to 90 miles (150 km)
from the center.
 
The estimated minimum central pressure is 991 mb (29.27 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
WIND: Tropical storm conditions are expected over Maui County and
the Big Island starting late Tuesday or Tuesday night. Tropical
storm conditions are expected over Oahu starting late Tuesday night
or Wednesday morning. Tropical storm conditions are possible over
Kauai County starting Wednesday afternoon.
 
RAINFALL: Olivia is expected to produce total rainfall accumulations
of 10 to 15 inches. Isolated maximum amounts of 20 inches are
possible, especially over windward sections of Maui County and the
Big Island. This rainfall may produce life-threatening flash
flooding.
 
SURF: Large swells generated by Olivia will spread from east to
west across the Hawaiian Islands over the next couple of days. This
will cause surf to build along exposed east facing shorelines as
Olivia approaches. This surf may become damaging across parts of the
state. See the High Surf Warning from National Weather Service
Honolulu for more information.
